EUGENE TERRY, OF WATERBURG, NEW YORK.

MOWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 249,116, dated November1, 1881, Application filed June 14, 1881. (No model.)

To all whom it may concern Be it known that I, EUGENE TERRY, ofWaterburg, in the county of Tompkins and State of New York, haveinvented certain useful Improvements in Mowing-Machines, of which thefollowing is a specification.

My invention relates to an improved means of connecting the cutter-barto the frame of a mowing-machine.

In order to equalize the draft it is common to connect the cutter-bar ofa mowing-machine to the forward end of the frame, at the corner thereoffarthest removed from the cutter-bar, by means ofa straight, or nearlystraight, coupling-arm. I have found, however, that certain objectionsto a straight coupling-arm may be overcome by using a curvedcoupling-arm and arranging the pitman-crank above the arm, so that thepitman shall work in the curve ofthe arm. This arrangement allows theshalt of the pitman-crank to be firmly supported by its forward bearing,and at the same time protects the crank from coming in contact with anyobstruction calculated to interfere with its action. I also provide abrace, which is attached to the rear of the arm and to the frame nearthe axle,'whereby a firm support .is afforded to the coupling-armwithout adding unnecessarily to the weight of the machine.

In the accompanying drawings, Figure l is a plan view of amowing-machine embodying my improvements. Fig. 2 is a front elevation ofthe same; and Fig. 3 is a cross-section thereof, taken on the line or xof Fig. 1.

Similar letters of reference indicate correspondin g parts.

The shaft A and the drive-wheels B B are of ordinary construction, theshaft being provided with the feathers a a and the hubs of the wheelsformed with the ratchetscc. Placed upon the shaft so as to engage withthe ratchets of the drive-wheels are the sliding clutchcollars d d,which are revolved with the shaft by means of the feathers a a, and areheld in close contact with the ratchets of the wheels by the springs it, which are placed upon the shaft between the said clutch-collars andthe fixed collars e c.

To the forward end of the frame 0, and to the left of the pitman-crankb, is hinged the coupling-bar D, which is curved downward, as shown, andis provided at the end which rests near the ground with the shoe andsmall wheel h, which runs upon the ground in front of the drive wheel.Jointed to the end of this bar is the cutter-bar H, which is provided onits under side with a shoulder, which comes against a correspondingshoulder on the end of the bar D, by which, when the bar D is raised bythe hand-lever, the cutter-bar will also be elevated for passing overobstacles and uneven ground. The bar D is braced from the frame of themachine by the rod E, which is linked to the rear side of the bar, andextends to the under side of the frame, as shown.

The frame of the machine is extended in rear of the shaft A, and thepitman-shaft F passes under the main shaft, and its rear end isjournaled in the bearing 7, formed in the frame in rear of the mainshaft, as shown in Fig.3, and the beveled cog-wheel K, which is adaptedto be moved on the'shaft by the lever G for throwing the machine in andout of gear, is in'rear of the main shaft and meshes with the beveledgear J, which is jonrnaled also in. rear of the main shaft, and receivesmotion from the large cog-wheel L upon the main shaft and the pinion L,formed upon the back of the beveled-gear wheel J. By this arrangementofthe gearing the weight thereof, being behind the shaft, counterbalancesthe weight ofthe forward part of the machine, and thus relieves the teamof a great deal of weight and renders the machine of lighter draft.

It will be understood that when the bar D is raised to elevate thecutting-bar to pass over obstructions, the action of the pitman g, whichpitman is of more than ordinary lengthviz., nearly the length of the barD-.-will not be much disturbed by the change in the position of theknives, but will operate smoothly and without cramping or unnecessarystraining, and that the bar also serves as a guard or pro tection to thecrank and pitman, making them less liable to bebent, broken, orotherwise injured.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-- In a mowing-machine, the combination of 100the pitman, the coupling-arm hinged in line with the pitman-crank andcurved downward, so as to extend beneath the pitman, and a brace, E,hinged to the rear of said couplingarm and to the frame near the axle,substam tially as shown and described.
